Kahukuranui was a Māori ariki (chieftain) of the Ngāti Kahungunu iwi and ancestor of the Ngāti Kahukuranui hapū of Te Aitanga-a-Hauiti. He led an expedition to Te Pōrangahau in order to avenge Tūpouriao and marry his widow Tū-teihonga. He may have lived in the fifteenth or sixteenth centuries.

Ngāti Kahungunu is a Māori iwi located along the eastern coast of the North Island of New Zealand. The iwi is traditionally centred in the Hawke's Bay and Wairārapa regions. The Kahungungu iwi also comprises 86 hapū (sub-tribes) and 90 marae.
